Nature-Based Solutions to Manage Storm Runoff in Urban Bengaluru – A Prelude

2024-03-22T11:29:47+00:00

Excess stormwater in urban areas leads to an emerging disaster like Urban floods. Urban flooding in recent times has received considerable attention globally due to its disastrous impacts owing to loss of human lives and damage to infrastructure. Urban flooding diverges from flash flooding by the fact that, with the advancements in urbanization, the urban flood increases from 1.8 to 8 times and flood volumes by up to six times. Rapid population growth and rampant urbanization over the years have encroached the existing water bodies resulting in a decrease in rainwater infiltration and increased runoff and flood rates.
This research paper examines the potential of nature-based solutions to manage storm runoff in urban Bengaluru. The study assesses the current state of stormwater management in the city and evaluates the effectiveness of different nature-based approaches, including green roofs, rain gardens, and permeable pavements. The results of the study demonstrate that nature-based solutions can significantly reduce the volume of stormwater runoff and improve water quality in urban areas. The study serves as a prelude to future research on the implementation and scalability of nature-based solutions for stormwater management in Bengaluru and other urban areas. Overall, this research suggests that nature-based solutions can provide a cost-effective and sustainable approach to manage storm runoff in Bengaluru and have the potential to improve the overall livability and resilience of the city.
